The PCV valve plays a critical role in your engine's emissions and crankcase ventilation system. It regulates the flow of blow-by gases from the crankcase back into the intake manifold for re-combustion, helping to reduce harmful emissions, prevent oil sludge buildup, and maintain proper engine pressure. A failed or clogged PCV valve can lead to oil leaks, rough idle, increased oil consumption, and reduced engine performance.
